The coronavirus has made millions around the world regularly wear masks to reduce the spread of the virus. It is clear, masks help mitigate virus spread<\/a>. But widespread mask wearing may be having another unintended benefit: lowering blood pressure for millions.<\/p>\n

With mask wearing to prevent coronavirus spread, people are accidentally protecting themselves from air pollution. Whoops!<\/p>\n

Let\u2019s take these subway riders I saw in Beijing in January. Everyone\u2019s masked up.<\/p>\n

\"Mask<\/p>\n

Well, except this guy, who seems to be floating blissfully in his own world.<\/p>\n

\"Mask<\/p>\n

 <\/p>\n

What are the Health Effects of Wearing a Mask?<\/h2>\n

Are all those masks doing anything? We can get a rough estimate of the effect size from this study<\/a>.<\/p>\n

\"Mark<\/p>\n

In this study, researchers randomly assigned people to wear N95 masks or no mask.<\/p>\n

\"N95<\/p>\n

Then they walked around central Beijing, near the Forbidden City (that rectangle on the right).<\/p>\n

\"masks<\/p>\n

While they walked, devices were tracking their blood pressure, heart rate, and other metrics. The masks lowered people\u2019s blood pressure and improved their heart rate variability<\/a>.<\/p>\n

\"masks<\/p>\n

Thus, we could infer that all this mask wearing is lowering people\u2019s blood pressure.<\/p>\n

But That\u2019s Just One Study <\/h2>\n

That\u2019s only one study, and there aren\u2019t many studies like this. However, another study<\/a> replicated the results. It\u2019s also consistent with studies<\/a> that have randomly assigned people to use their air purifiers at home and found that it lowered their blood pressure<\/a>.<\/p>\n

\"Masks<\/p>\n

But Those Are N95s…<\/h2>\n

OK, OK, but those are N95 masks. For the coronavirus, lots of people are wearing weaker surgical masks or even cloth masks. Those things can\u2019t capture tiny pollution particles, right?<\/p>\n

\"Cloth<\/p>\n

The data is surprising. Let\u2019s take an extreme example. Researchers tested<\/a> a cheap surgical mask they bought off the streets of Kathmandu<\/strong>.<\/p>\n

\"Street<\/p>\n

Let\u2019s look at 1-micron particles. Those are about 1\/60th the width of a human hair<\/a>.<\/p>\n

\"Air<\/p>\n

For those particles, the surgical mask captured as much as the N95 mask\u2014over 90%.<\/p>\n

\"Masks<\/p>\n

For the smallest 0.03-micron particles (30nm), the N95 did better. But the cheap surgical mask still captured over 60%. Surprising, no? But this is just one of several studies that have found that surgical masks are surprisingly effective against pollution<\/a>, even after taking into account how tightly they fit.<\/p>\n

Bottom Line<\/div>
<strong>Bottom line: Masks may be lowering blood pressure for millions<\/strong><\/div>
Based on the data, we could estimate that cotton and surgical masks could improve people\u2019s blood pressure and heart rates. Those effects might be approximately 30\u201350% of the effect of N95 masks.<\/div>

\"Masks<\/p>\n

P.S. Caveat<\/strong>
\nThis data doesn’t address gas pollutants like NO2 and O3. Masks like N95s capture particles, not gases. Thus, they\u2019re good, but not 100% protection. But they\u2019re good enough for me to bike through Delhi traffic.<\/p>\n

\"Masks<\/p>\n\n\n

WHAT NEXT?<\/h2>\n\n\n\n

Along with wearing masks, air purifiers with HEPA filters are also one of the best ways to stay safe from a variety of pollutants in our air including viruses and dangerous PM2.5. A recent CDC study confirmed significantly lower COVID-19 infection rates in schools<\/a> that used HEPA air purifiers. HEPA filters can significantly lower the risk of a variety of deadly diseases<\/strong> including diabetes, heart disease, cancer, and high blood pressure.<\/p>\n\n\n\n
